Short interest ratio should be Short squeeze duration or Short cover duration Margin should be Loan value Arbitrage/Parity should be Price imbalance Gamma squeeze is wrong...it should be Gamma dump since gamma drops as volatility spikes. Yes when volatility spikes, shorts can get trapped, and thus squeezed...so we are applying the squeeze to gamma for some reason...probably because it sounds cool lol. Theta decay should be Price decay because theta isn't decaying...its increasing. I realize the term is conjoining the idea that price is decaying from the theta increasing but it can be confusing to people...also sounds cooler I guess. I'm noticing a lot of these terms are to try to sound cool. Risk reward has always bothered me because its easier to say risk reward, but the ratio looks and sounds better with the higher number first ie 3:1...but that would be a terrible risk reward. So you either put 3:1 and call it reward to risk which sounds cumbersome, or you have 1:3 and call it risk reward, but the numbers don't look or sound right. Better to be done with the ratio entirely and use Return on risk. Splits should be 10 for 1 not 10:1, and reverse splits should be 1 for 10 instead of 1:10.
OK, I'll play. Short interest ratio should be Short interest ratio Margin should be Required Equity Arbitrage/Parity should be Mispricing Arb Gamma squeeze should be Short Vol Squeeze Theta decay should be Price decay So where is Anytown?
I always wondered where that jargon appeared for the first time. It would be interesting to read something about the origins of that naming convention.
IMO they start on trading floors like the CBOE, NYSE and CME. Then Business media programs like the ones on CNBC have guests from those floors or trade desks that use those terms.
I had to learn hand signals on the AMEX. They differ on every floor. So does the language used to announce your orders or market in that Pit or Crowd.
AB = CD pattern should really be CD = AB because that is the way price plots left to right (AB is in the past, locked in place - CD is then compared to it), but the anal-retentives need alphabetical order maintained to be right with the world.
bc the clerk isn't allowed to yell and it's quicker than running to the pit. It's an arb relative to the runner with an order slip.
For a long time they arb'd the big floor traded S&P contract vs the emini. They would have one guy on the screen and one in the pit and used the hand signals to balance up their book.
